OMG... after putting my copy of the filter invention in my pond yesterday, I couldnt believe how much gunk got caught up in it! kudos to the inventer and you coulda made a million off that! I cleaned my pond out today- figured the fish would like some clean cooler water since its been so hot (100 degrees today) got a couple questions for any of you- I have 2 lillies in the pond I bought this spring- am I doing them harm by changing water temp and clarity and messing with hight for a time? last question for the night is, am I doing my pond harm by fussing over it too much? I just want a pond that has clear-ish water and dont mind the green tint to it- its concrete if thats a factor (Im sure it is) any help with my questions would be greatly appreciated =) ty in advance!
